docker-ruby

This repository provides Rocky Linux-based Ruby Docker images.

Build

Create a builder:

docker buildx create --use --name builder

Build for linux/amd64 and export images to the default image store (docker images):

docker buildx bake --load

Build for a different or multiple architectures:

docker buildx bake --load --set="*.platform=linux/amd64,linux/arm64"

Note that building images for multiple architectures requires one of the following:

• Containerd image store for the --load flag to work
• Pushing directly to a registry, e.g. docker buildx bake --push --set="*.platform=linux/amd64,linux/arm64"
• Using other output types or omitting output flags to keep build cache only
